For this question, I first used a
map<char,char> for doing the replacement according to the rules.
map<char,char> m; m[ci] = pi;
Did not work. After a lot of struggling, I finally thought of doing asserts to check whether the final string I’m getting is actually a decimal number. So I counted number of dots ‘.’ and that assert failed.
assert(dots <= 1);
I couldn’t get AC, so I thought of just using a char array to do the same mapping from ci -> pi
char m; memset(m,' ',1000); m[ci] = pi;
Surprisingly this worked. Those two solutions differ at only 3 lines ( line #13, #18, #30). Can someone tell me what’s wrong with the
